When Moby Dick arrived at Noyomi Island, Ali noticed that the island was a huge forest. He was shocked to see that the animals in the forest were very large; they were larger than those on Rusukaina Island, where Luffy had trained with Rayleigh during the time skip.
Whitebeard, Ali, and the rest of the Whitebeard pirate commanders disembark the ship and start walking deeper into the forest.
Ali noticed a massive white mountain in the middle of the forest, with clouds covering the top half of the mountain.
Ali smiled when he saw this and thought to himself, "Grand Line is really a mysterious place. I am grateful that I have reincarnated in the One Piece universe."
Whitebeard then said to Ali, "Little Ali, do you see the big white mountain in the middle of the forest?"
When Ali heard Whitebeard's question, he nodded his head. Whitebeard continued, "The area around the mountain is the safest area in the forest." If you wish to rest and sleep, head there; the forest animals never approach the areas around the mountain."
Ali nodded his head in understanding, and Whitebeard continued, "Now listen up. As I said yesterday, I will allow you to leave Moby Dick, but you have to do a few things first. You will need to learn the basics of Haki; you need to master the basics of at least two types of Haki."
When Ali heard this, his eyes widened, and Whitebeard continued, "Next, I will leave you on this island. You will need to survive here; once a month, I will come check on you and see your progress." Whenever I come back, you'll spar with me and the other commanders."
Ali, upon hearing this, smiled and nodded his head in agreement. Whitebeard then said, "If you are able to impress me when we spar and you master the basics of at least two types of Haki, I will let you leave Moby Dick."
While Whitebeard was engaged in conversation with Ali, an enormous black-furred bull suddenly charged towards them. Ali's eyes widened when he saw the bull's size—it was larger than a typical house.
Whitebeard smirked when he saw the black-furred bull and then said to Ali and to the commanders of the Whitebeard pirate, "My sons, step back; this is a great opportunity to explain Haki to little Ali."
Ali, along with the other commanders of the Whitebeard pirate, took a couple of steps back. Whitebeard addressed Ali, saying, "Listen, little Ali, Haki is dormant in every living creature, but most people around the world never even learn about its existence, let alone how to utilize it." "Those who do typically awaken it through proper instruction and intense training, but it usually takes a lot of effort and time even for those who had incredible talent."
Ali nodded as he continued to listen to Whitebeard. "Some people may awaken Haki without training or instruction if they experience extreme stress or shock." Furthermore, it is possible for some individuals to be born with awakened Haki, although this is a rare occurrence."
Ali contemplated what Whitebeard had just said and thought to himself, "Just like Koby when he awakened observation Haki in the Marineford War and Aisa, who was born with observation Haki in Skypea."
Whitebeard then continued saying, "Now I will explain to you every type of Haki first. The first type of Haki I am going to explain to you is called observation Haki: This Haki gives the user a sixth sense of the world, allowing them to sense others' presence, strength, and emotions, whether they are nearby or far away. It also grants limited precognitive abilities, allowing the user to sense their opponents' intentions and predict their actions and attacks before they happen."
"GROWL."
The bull roared at Whitebeard and charged at him to impale Whitebeard with its horn.
When Whitebeard saw this, he closed his eyes and said, "Little Ali, watch carefully."
Every time the black-furred bull charged at Whitebeard and was about to impale him with its horn, Whitebeard would sidestep and dodge the bull.
When Ali noticed Whitebeard evading the black-furred bull's attacks with his eyes closed, his eyes widened, and he thought to himself, "Whitebeard is predicting the bull's attacks; this is really amazing."
Whitebeard continued dodging the black-furred bull's attacks and said to Ali, "What you are seeing is me using the observation Haki to predict the bull's attacks; now I am going to show the other type of Haki, the Armament Haki."
Whitebeard's left palm abruptly turned black, and an orange aura surrounded it. As the bull charged at him, Whitebeard tapped his palm in the air in front of its forehead.
"BAAM."
Suddenly, after Whitebeard tapped the air with his left palm, the black-furred bull fell into the ground unconscious.
When Ali witnessed this, he was shocked and thought to himself, "Incredible, he just tapped the air around Bull's forehead, and the bull fell unconscious into the ground." I had never witnessed such a scene in the anime; perhaps it's because I passed away while the One Piece anime was still in the Dressrosa arc, and more Haki usage was revealed later on in the story."
Whitebeard then said to Ali, "Armament Haki allows the user to use their own spiritual energy as invisible armor to defend against attacks, as well as make their own attacks more potent. It can also be used to bypass Devil Fruit defenses, such as the intangibility of a Logia. A person can also apply the armament haki to a section of their body, their entire body, and even imbue it onto their weapons."
"GROWL."
Suddenly a huge black bear appeared and charged at Whitebeard, and Whitebeard chuckled. When he saw this, the bear swung its claws at Whitebeard, and Whitebeard grabbed its claws with his left hand while coating it with Armament Haki.
"CLANK."
A metallic sound accompanied the bear claw's impact. Whitebeard then addressed Ali, saying, "Now, the last type of Haki is a special kind of Haki because it is innate; only one out of one million has a chance of awakening this Haki." In other words, you can't train to awaken this Haki. It's called Conqueror Haki. Now watch carefully, little Ali."
Whitebeard glared at the black bear, and an invisible force shot out from him towards the bear. The black bear's eyes turned white, and foam erupted from its mouth before falling unconscious nto the ground.
"THUD."
Whitebeard then turned around, looked at Ali while smirking, and said, "That's all the help I'm going to give you. Whether you learn and master the basics of Haki is all up to you, little Ali."
Ali widened his eyes in surprise when he heard this and asked Whitebeard, "Wait a second, aren't you going to teach me how to awaken and train my Haki father?"
Whitebeard narrowed his eyes and said seriously to Ali, "Ali, if you want me to give everything to you on a silver plate, you should give up on your ambition right now."
When Ali heard this, his eyes widened, and Whitebeard turned around and began walking away. The commanders too followed Whitebeard.
Ali then heard Whitebeard saying, "What I showed you is the tip of the iceberg. Haki is deeper than this. See you next month, Ali."
Ali widened his eyes when he heard this, and he thought to himself, "Just like I thought. Oh well, I shouldn't concern myself with an advanced application of Haki; I should focus on improving my swordsmanship and mastering the basics of Haki right now."
Ali then looked at Whitebeard and the other commanders; he saw them getting on Moby Dick and sailing away from the island.
Ali sighed to himself, "Well, father is right; if I want everything to be given to me easily, I should give up on my ambition."
Ali then started walking towards the huge white mountain.
